一、使用 json_encode 输出<?php
header('content-type:application/json;charset=utf8');
$arr = array(
'status' => true,
'errMsg' => '',
'member' =>array(
array(
'name' => '李',
'gender' => '男'
),
array(
'name' => '赵',
'gender' => '女'
)
)
);
echo json_encode($arr);
?>
(推荐学习：PHP视频教程)
输出：{"status":true,"errMsg":"","member":[{"name":"\u674e","gender":"\u7537"},{"name":"\u8d75","gender":"\u5973"}]}
二、使用 jsonFormat 输出<?php
/** Json数据格式化
* @param Mixed $data 数据
* @param String $indent 缩进字符，默认4个空格
* @return JSON
*/
function jsonFormat($data, $indent=null){
// 对数组中每个元素递归进行urlencode操作，保护中文字符
array_walk_recursive($data, 'jsonFormatProtect');
// json encode
$data = json_encode($data);
// 将urlencode的内容进行urldecode
$data = urldecode($data);
// 缩进处理
$ret = '';
$pos = 0;
$length = strlen($data);
$indent = isset($indent)? $indent : ' ';
$newline = "\n";
$prevchar = '';
$outofquotes = true;
for($i=0; $i<=$length; $i++){
$char = substr($data, $i, 1);
if($char=='"' && $prevchar!='\\'){
$outofquotes = !$outofquotes;
}elseif(($char=='}' || $char==']') && $outofquotes){
$ret .= $newline;
$pos --;
for($j=0; $j
$ret .= $indent;
}
}
$ret .= $char;
if(($char==',' || $char=='{' || $char=='[') && $outofquotes){
$ret .= $newline;
if($char=='{' || $char=='['){
$pos ++;
}
for($j=0; $j
$ret .= $indent;
}
}
$prevchar = $char;
}
return $ret;
}
/** 将数组元素进行urlencode
* @param String $val
*/
function jsonFormatProtect(&$val){
if($val!==true && $val!==false && $val!==null){
$val = urlencode($val);
}
}
header('content-type:application/json;charset=utf8');
$arr = array(
'status' => true,
'errMsg' => '',
'member' =>array(
array(
'name' => '李',
'gender' => '男'
),
array(
'name' => '赵',
'gender' => '女'
)
)
);
echo jsonFormat($arr);
?>
输出：{
"status":true,
"errMsg":"",
"member":[
{
"name":"李",
"gender":"男"
},
{
"name":"赵",
"gender":"女"
}
]
}
三、php5.4 以后，json_encode增加了JSON_UNESCAPED_UNICODE , JSON_PRETTY_PRINT 等几个常量参数。使显示中文与格式化更方便。<?php
header('content-type:application/json;charset=utf8');
$arr = array(
'status' => true,
'errMsg' => '',
'member' =>array(
array(
'name' => '李',
'gender' => '男'
),
array(
'name' => '赵',
'gender' => '女'
)
)
);
echo json_encode($arr, JSON_UNESCAPED_UNICODE|JSON_PRETTY_PRINT);
输出：{
"status": true,
"errMsg": "",
"member": [
{
"name": "李",
"gender": "男"
},
{
"name": "赵",
"gender": "女"
}
]
}
